<P>PROBLEM TO BE SOLVED: To provide a cartridge for a discharge gun which stops immediately to discharge a fluidity material when a lever of a discharge gun for discharging the fluidity material is returned from a cartridge. <P>SOLUTION: The tube 2 of the cartridge for the discharge gun is composed of a film object. The annular part 5a of a plunger 5 is inserted in the inner surface of the base end part of the tube 2 so that it can be slid. The projection part 5c is formed on the inner surface of the distal end portion of the annular part 5a. The circumferential part of a shielded part 5d comprised of the film object is stuck on the distal end face of the projection part 5c. The more inner side part from the projection part 5c of the shielded part 5d is formed to be a slackened part of a slackened state so that it can be switched from the state evaginated globularly towards the reverse to become a strained state to the state evaginated globularly towards the front. <P>COPYRIGHT: (C)2008,JPO&INPIT |
